摘要
采用微波耦合超声波技术处理柴油污染土壤,考察其可行性,并研究不同条件对污染土壤的处理效果。结果表明,此技术可行且在微波功率700 W,微波辐照时间13 min,超声功率400 W,超声时间5 min,含水率20%等条件下,实验装置运行稳定,柴油污染土壤中油类去除率可达86.4%,明显高于单独微波辐照时的去除率。
The technology of microwave-ultrasonic has been adopted to treat diesel contaminated soil.The feasibility and the effect of this technique was studied under different conditions.It was found that when the soil was 20 % in moisture content,13 minutes irradiation with 700 W microwave,and 5 minutes irradiation with ultrasonic 400 W,the experimental device running stable and the diesel removed rate was 86.4%.The removal rate was significantly higher than when the microwave irradiation alone.
